i DIRECTIONAL AUTOMOBILE HEADLIGIHT. i

`Appnmnm inea August 2o, 1924. serialv iro. 'zaosa This invention relatesto automobile headlights of the character described and claimed in my copending., application, Serial No. 715,795, led May 26, 1924, wherein I disclosed a headlight having a movable -reflector controlled by the actionv of centrifugal force, whereby'the movement of a car4 in changing `direction wasv instrumental in automatically shifting the reflector to-light the path of the car. In the said'prior invention, the whole reflector ywas bodily movl ableunder the action of centrifugal lforce, as specified, and because of the .relatively wide angle through which the reflector Vwas V adapted to move, a special form of lamp housing was desirable in order that all of the rays of' the lamp might be emitted from the housing witliout-blanketing.

, 1 The robject of the present invention is to improve upon the former constructionmore particularly by permitting the use of the conventional lform of lamp housing coin- `monly employed on automobiles so thatthe use of a special housing is not necessary. The lamp of the present invention, in contradistinction to the former one, ,embodies two reflectors, oneof which is, to all intents and l purposes, substantially identical' with the- 'well known conventional reflector, being lmounted vinistationary position within the housing in the usual manner. i The lamp is positioned in cooperative 'relationto this stationary reflector but between the lamp and ysaid refiectoris positioned a'supplementary reflector of smaller sizethan the Otherand Ymounted for rotation on a vertical axis which includes thelamp; `The movement of thislatter reflector is controlled by centriful gal' .force and is capable Y of movement through a wide angle without yblanketing anyl'of the bea-m.

An important'feature vof the Vpresent construction resides in the factftliat the invention may be applied to a conventional `lamp in a simple and economical manner and .a

'further important?consideration resides in the fact-'that while the greater portion of the light fromthe bulb is directed into the path ofthe car, the remainderlof ythe light from.

saidy source isV directed substantially straight ahead of. tliecar at all times. This is an `advantage especially on country roads since the major .beam from the movablereector lights there@ Of the a? ivhiath@ SGH-1221;@-

ary beam from-the fixed reflector gives `a lighter but less brilliant zone of vision, so

that in the event of emergency the driver is better able to act. l .l

Features of the invention, other thanthose adverted to, willr beapparent from the herej inafter detaileddes'cription and claims, when i read in conjunction with the accompanyingy drawings.

The accompanying 'drawings illustrate one practical embodiment ofthe invention, but

the construction therein shown is to be uiiderstood as illustrative, only, and Anot as ,i

defining the limits of the invention.

Figure 1 is a central `vertical, section through a .headlight embodying they present invention and, l. l i. Figure 2`is a horizontal section onzthe line 2-2Aof Figure 1.

Referring to the drawings, lidesignates l alamp housing which, finpractice, may be of theconventional form now v` in vogue. With this ycasing is associatedv the usual fixed reflector 2 and lens 3 heldin vplace by a vsplit ring as is common. ".The housing is provided with a supporting stem, 5. l

Thev foregoing parts are well known and are in common use. rIn associating the pressupporting standard 6L yadapted to project Current is supplied to the bulb, through a ywire `10 which passes through the hollow standard 6 to the socket 8.

' free rotation. The-carrier is .provided vwith 'eiit-`- invention witha lamp housing of tthis character, Il mount within the stem 5 a bulb ,through anopening formed in the lfixed reflector and to the `upper end ofthis standard attach a socket 8 to receive the bulb 9.

anupstanding arm or bracket 12 and this bracket carries a reflector 14 vrwhich is positionedwithin the reflector lZand'back ofthe bulb 9, J The reflector*y ,14 isf considerably smaller than .thereliector 2, as will ,be seen from Figure l-of thedrawings, butis soy vpositioned with respect/to the source of light that the greater portionofthe light f -from such j source is received `and deflected from the reflector 14.

which extendsrearwardly and carries there- 'pii-.afroller-i adepte@ srseeceretiseritli sov by m of 'a Weight 2O securedto the end or" the l in beyond the roller 16.

' Throug-li the utilization of the Weight 20, the roller is normally manta-ined midvvay of the I9 and in such position that lthe light im'pingi'ng "thev reflector 14' is directed strai tahea-d. Ixf, however, the car with Whicliithe"headlight is associated .changes direction, centrifugal Ytorce `will act upn the iveightZO'to carry: it ina lateral direction afterthe manner'fully described and claimed inf'rny said 'cepee-ding'y case', Vjwherein the stabi'li'zeig'asI yvell as 'the Weight 20 Wheel 16 and, arm "15' function in chef-identical manner as vherein yslloltii.

The angular de- {iection is manifestly controlled Vbyv the degreeofcurvature 'ofthe road which the car is' traversing', yand vit isy `found in practice that'the major beam from' the reflector 14 uiillilluminate theti'u'e path of the car in negotiating a turn.
